■Running out of fuel
When the vehicle has run out of fuel and
the hybrid system cannot be started, refuel the vehicle with at least enough gasoline to make the low fuel level warn-
ing light ( P.541) go off. If there is only a small amount of fuel, the hybrid sys-tem may not be able to start. (The stan-
dard amount of fuel is about 8.8 L [2.3 gal., 1.9 Imp.gal.], when the vehicle is on a level surface. This value may vary
when the vehicle is on a slope. Add extra fuel when the vehicle is inclined.)
■Electromagnetic waves
●High voltage parts and cables on the Plug-in Hybrid Electric Vehicles incor-porate electromagnetic shielding, and
therefore emit approximately the same amount of electromagnetic waves as conventional gasoline pow-
ered vehicles or home electronic appliances.
●Your vehicle may cause sound inter-ference in some third party-produced radio parts.
■Effect of magnetic forces
If objects that generate strong magnetic forces, such as large speakers, are placed inside the luggage compartment
or installed nearby, the generated mag- netic forces may negatively affect the hybrid system.
■Hybrid battery (traction battery)
(lithium-ion battery)
The hybrid battery (traction battery) has a limited service life.
The hybrid battery (traction battery) capacity (the ability to hold a charge) reduces with time and use in the same
way as other rechargeable batteries.
The extent at which capacity reduces changes drastically depending on the
environment (ambient temperature, etc.) and usage conditions, such as how the vehicle is driven and how the hybrid bat-
tery (traction battery) is charged. This is a natural characteristic of lithium-ion batteries, and is not a malfunction. Also,
even though the EV driving range becomes shorter when the hybrid bat-tery (traction battery) capacity reduces,
vehicle performance does not signifi- cantly become worse.
In order to reduce the possibility of the
capacity reducing, follow the directions listed on P.133, “Capacity reduction of the hybrid battery (traction battery)”.
■Starting the hybrid system in an
extremely cold environment
When the hybrid battery (traction bat- tery) is extremely cold (below approxi-
mately -30°C [-22°F]) under the influence of the outside temperature, it may not be possible to start the hybrid
system. In this case, try to start the hybrid system again after the tempera-ture of the hybrid battery increases due
to the outside temperature increase etc.
■Declaration of conformity
This model conforms to hydrogen emis- sions according to regulation ECE100
(Battery electric vehicle safety).

WARNING
■High voltage precautions
The vehicle has high voltage DC and AC systems as well as a 12-volt sys-tem. DC and AC high voltage is very
dangerous and can cause severe burns and electric shock that may result in death or serious injury.

WARNING
●Never touch, disassemble, remove or replace the high voltage parts,
cables or their connectors.
●The hybrid system will become hot
after starting as the system uses high voltage. Be careful of both the high voltage and the high tempera-
ture, and always obey the caution labels attached to the vehicle.
●Never try to open the service plug access hole located in the luggage compartment. The service plug is
used only when the vehicle is ser- viced and is subject to high voltage.
■Road accident cautions
Observe the following precautions to reduce the risk of death or serious
injury:
●Pull your vehicle off the road, apply
the parking brake, shift the shift lever to P, and turn the hybrid sys-tem off.
●Do not touch the high voltage parts, cables and connectors.
●If electric wires are exposed inside or outside your vehicle, an electric
shock may occur. Never touch exposed electric wires.
●Do not touch the battery if liquid is leaking from or adhering to it.If electrolyte (carbonic-based
organic electrolyte) from the hybrid battery (traction battery) comes into contact with the eyes or skin, it
could cause blindness or skin wounds. In the unlikely event that it comes into contact with the eyes or
skin, wash it off immediately with a large amount of water, and seek immediate medical attention.
●If electrolyte is leaking from the hybrid battery (traction battery), do
not approach the vehicle. Even in the unlikely event that the hybrid battery (traction battery) is
damaged, the internal construction of the battery will prevent a large amount of electrolyte from leaking
out. However, any electrolyte that does leak out will give off a vapor. This vapor is an irritant to skin and
eyes and could cause acute poi- soning if inhaled.
●Do not bring burning or high-tem-perature items close to the electro-lyte. The electrolyte may ignite and
cause a fire.
●If a fire occurs in the Plug-in Hybrid
Electric Vehicle, leave the vehicle as soon as possible. Never use a fire extinguisher that is not meant
for electric fires. Using even a small amount of water may be danger-ous.
●If your vehicle needs to be towed, do so with front wheels raised. If the
wheels connected to the electric motor (traction motor) are on the ground when towing, the motor may
continue to generate electricity. This may cause a fire. ( P.529)

2-2. Charging
Plug-in hybrid system
This product must be grounded. In
case of malfunction or break down,
grounding provides a path of least
resistance for electric current to
reduce the risk of electric shock.
This product is equipped with a
grounding conductor and a ground-
ing plug. The grounding plug must
be plugged into an appropriate
socket that is properly installed and
grounded in accordance with all
local codes and ordinances.
The CCID (Charging Circuit Inter-
rupting Device) has the following
safety features.
■Electrical leakage detection
function
If an electrical leakage is detected
during charging, the power source
will be automatically interrupted,
thus preventing fires or electrical
shocks caused by electrical leak-
age.
If the power source is interrupted, the
error warning indicator flashes.
If the power source is interrupted:
 P.114
■Automatic check function
This is an automatic system check
that is run before charging begins
to check for problems in the opera-
tion of the electrical leakage detec-
tion function.
If a malfunction is found in the electrical
leakage detection function as a result of
the check, the error warning indicator
flashes to inform the user. ( P.114)
■Temperature detection func-
tion
A temperature detection function is
equipped to the plug. While
charging, if heat is generated due
to looseness on the socket side
etc., this function suppresses heat
by controlling the charging current.
■Conditions for supplying cur-
rent to the vehicle
The CCID (Charging Circuit Inter-
rupting Device) is designed to pre-
vent electrical current from being
supplied to the charging connector
when it is not connected to the
vehicle, even if the plug is inserted
into the socket.
Grounding (Mode 2 AC
charging cable)
WARNING
■Grounding precautions
●Improper connection of the ground-
ing conductor increases the risk of electric shock.Check with a qualified electrician or
serviceman if you are in doubt as to whether the product is properly grounded.
●Do not modify the grounding plug provided with the product. If it does
not fit the socket, have a proper socket installed by a qualified elec-trician.
